Grid-tied solar

A suggestion, create a Word or Excel file, save file, then save as a .jpg or .bmp and upload the pic. No editing required and the original file can be updated and preserved.

Thanks. That's a good suggestion. I try to keep simple things simple though. A WSIWYG editor would make it easy but I think what I have will do good enough.

Yeah, I'd do excel spreadsheet and then use the snipping tool in W7 to make a picture of it.

+1 I use the snipping tool often when I just need a low resolution image.

Results for February 2015. The best February so far.

I am too far away from an accurate model location to get conforming results. Portland is the most accurate by station class but farther away. Waterville comes closest to my actual annual results but the deviation for some months is very large.

A "Value of Solar" study commissioned by the Maine PUC. I haven't read through all 178 pages yet but there is some interesting info regarding many facets of alternative energy and the grid, future electric costs, even a calculation about the reserve capacity needed by wind turbines! (See page 80)

Results for March 2015.

A great March. Clear skies generally go with colder weather and this March has been colder than average.

I will believe when I see it work for the long haul, which I hope it does.

Always these breathless exciting news stories about new ground breaking battery or solar cell tech. The promises all disappear when the government research grant or the private investor money runs out.
Last time I looked there have been no new elements added to the periodic table. So don't be expecting new rechargeable battery tech.
